英文摘要 | Conductive carbon films with good flexibility are ever-increasingly desired for electronics. Previous efforts relying on graphene films to achieve this required special treatment to create wrinkles in the lamellar stacking sheet structure. Here, films with a wrinkled structure were facilely fabricated from electrochemically derived 3-dimiensional (3D) graphene/graphite aggregates, exhibiting excellent flexibility and high conductivity. The resulting films are very flexible that can bear 1000 times fold without breakage. A high conductivity up to 100 000 S m(-1) can be achieved after a relatively low temperature annealing (1000 degrees C) owing to its low content of defect and large size of graphene/graphite aggregates. Based on these properties, an electrothermal heater assembled from these composite films supplies a high saturated temperature (423 degrees C) at low working voltages (4 V). These superior properties, together with the advantage of environmental friendliness and facile and large-scale fabrication, endow the composite films with great potential applications in flexible electronics. |
